WELDED HEADER FOR PRESSURE TRANSMITTER

摘要

A pressure transmitter comprises a metal wall separating a process pressure chamber from an electronics compartment. The metal wall has a stepped bore with a bore shelf facing the process pressure chamber. A metal header has a stepped outer rim with a header shelf that contacts the bore shelf. The metal header includes at least one electrical feedthrough with a glass-to-metal seal adjacent the stepped outer rim. A welded seal seals the stepped outer rim to the stepped bore.
